The usage of frequencies within the United States is regulated by the Federal Communications Commission (FCC). The US is then divided geographically into a number of Trading Areas. A mobile operator (or other interested parties) must bid on each trading area individually. A bidder can use the frequency spectrum for whatever purpose they want. Go to Wireless Advisor for a listing of the network operators for a given ZIP code.

The 869–894 MHz cellular band is divided into 2 frequency blocks (A and B). There are 306 Metropolitan Service Areas and 428 rural service areas. Each trading area consists of one or more counties.

The 1850–1990 MHz PCS band is divided into six frequency blocks (A through F). Each block is between 10 MHz and 30 MHz bandwidth. License (A or B) is granted for a Major Trading Areas (MTAs). License (C to F) is granted for a Basic Trading Areas (BTAs). There are 51 MTAs and 493 BTAs in the United States.

The AWS bands, auctioned in the summer of 2006, were for 1,710–1,755 MHz, and 2,110–2,155 MHz. The spectrum was divided into blocks: A blocks were for Cellular Market Areas, based on existing cellular (1G) licenses, and were 2 × 10 MHz. B and C blocks (2 × 10 MHz and 2 × 5 MHz respectively) were for Basic Economic Areas, larger than CMAs, usually comprising large portions of single states. D, E, and F blocks covered huge areas of the country, typically several states at a time, and covered 2 × 5 MHz for D and E blocks, 2 × 10 MHz for F.

The 700 MHz band was auctioned in early 2008 using spectrum previously used by television stations' analog broadcasts, with Verizon Wireless and AT&T Mobility winning the majority of available spectrum. Qualcomm and Echostar were winners of a significant amount of broadcast-oriented spectrum. Verizon Wireless has announced they are using the lower band of the 700 MHz spectrum to deploy their LTE network starting on Dec 5, 2010.

The SMR 800 MHz band was used exclusively for iDEN technology, however, Sprint Nextel is deploying CDMA and LTE technology on this band. As of 2 September 2011 (2011 -09-02), the FCC has approved several CDMA devices for use on the SMR band.

More bands are under consideration for auction by the FCC. These are currently used by DoD, NASA, and other government agencies.

Cellular and PCS bands are also used in other countries in the Americas.

Famous quotes containing the words united states, frequency, bands, united and/or states:

    America—rather, the United States—seems to me to be the Jew among the nations. It is resourceful, adaptable, maligned, envied, feared, imposed upon. It is warm-hearted, overfriendly; quick-witted, lavish, colorful; given to extravagant speech and gestures; its people are travelers and wanderers by nature, moving, shifting, restless; swarming in Fords, in ocean liners; craving entertainment; volatile. The schnuckle among the nations of the world.
    Edna Ferber (1887–1968)

    The frequency of personal questions grows in direct proportion to your increasing girth. . . . No one would ask a man such a personally invasive question as “Is your wife having natural childbirth or is she planning to be knocked out?” But someone might ask that of you. No matter how much you wish for privacy, your pregnancy is a public event to which everyone feels invited.
    Jean Marzollo (20th century)

    “Do not be afraid; for see -I am bringing you good news of great joy for all the people: to you is born this day in the city of David a Savior, who is the Messiah, the Lord. This will be a sign for you: you will find a child wrapped in bands of cloth and lying in a manger.”
    Bible: New Testament, Luke 2:10 -12.

    Angels to the Shepherds.

    There is no Soviet domination of Eastern Europe and there never will be under a Ford administration.... The United States does not concede that those countries are under the domination of the Soviet Union.
    Gerald R. Ford (b. 1913)

    Sean Thornton: I don’t get this. Why do we have to have you along. Back in the states I’d drive up, honk the horn, a gal’d come runnin’ out.
    Mary Kate Danaher: Come a runnin’. I’m no woman to be honked at and come a runnin’.
    Frank S. Nugent (1908–1965)
